Question

In SQL Server for CURSOR we say:

CREATE PROCEDURE SP_MY_PROC
                (@BANKID VARCHAR(6)='')
-------------------------------
-------------------------------

  DECLARE MY_CURSOR CURSOR FOR
    SELECT .......

Now, what I wonder, can we determine the select statement according to a cerain condition?

IF BANKID<>''// SELECT * FROM EMPLOYESS WHERE BANKID=@BANKID to be the cursors query
ELSE  // otherwise SELECT * FROM EMPLOYEES  to be the cursors query   

Or does it have to be static?

Yes, you can do this with Dynamic SQL

IF @BANKID<> ''
    SET @sql = '
       DECLARE MyCursor CURSOR FOR
          SELECT ...'
ELSE
    SET @sql = '
       DECLARE MyCursor CURSOR FOR
          SELECT ...'

EXEC sp_executesql @sql 
OPEN MyCursor
